`embedded-io`

This project is developed and maintained by the HAL team.

Input/Output traits for embedded systems.

Rust's std::io traits are not available in no_std targets, mainly because std::io::Error requires allocation. This crate contains replacement equivalent traits, usable in no_std targets.

The only difference with std::io is Error is an associated type. This allows each implementor to return its own error type, while avoiding dyn or Box. This is how errors are handled in embedded-hal.

Minimum Supported Rust Version (MSRV)

This crate is guaranteed to compile on stable Rust 1.59 and up. It might compile with older versions but that may change in any new patch release.

See here for details on how the MSRV may be upgraded.
